With the popularity of sharing-based applications such as bicycle and car sharing,
the sharing economy has attracted considerable global attention. The factors that affect users’ adoption
of the sharing economy must be identified to facilitate the promotion of low-carbon lifestyles and
help enterprises attract more active users. By employing the technology acceptance model (TAM)
and herd behavior, this study implemented an expanded TAM and identified several factors affecting
behavioral intention (BI) toward the sharing economy. A questionnaire was used to obtain the data,
which were analyzed through structural equation modeling. The results revealed that perceived
usefulness (PU) and perceived ease of use (PEOU) are the main factors affecting BI. Moreover,
trust (TRU) was identified as a mediator of subjective norm (SN) and PEOU. Imitating others
(IMI) affects BI, and SN affects TRU, PU, and PEOU. Gender moderates SN and IMI. This paper
indicates that to improve users’ BI, enterprises should enhance PU, PEOU, and TRU; cooperate with
organizations to enhance SN; and guide potential users to imitate others.
